CD5.CAR/28 T Cells, Cyclophosphamide, and Fludarabine in Treating Participants with Recurrent T-Cell Malignancies Expressing the CD5 Antigen

Trial Status: active

This phase I trial studies the side effects and best dose of autologous (derived from cells collected from the patient) or allogeneic (derived from previous stem cell transplantation donors cells) CD5-specific CAR-28 zeta CAR T-cells (CD5.CAR/28 T cells) when given together with cyclophosphamide and fludarabine in treating participants with T-cell cancers expressing the CD5 antigen that that has come back. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells including tumor cells. The antibody used in this study is called anti-CD5, which sticks to T-cell leukemia or lymphoma cells because of a substance on the outside of these cells called CD5. The T cells will also contain a substance called CD28 which may help stimulate the T cells and may make them last longer. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving CD5.CAR/28 T cells with cyclophosphamide and fludarabine may work better in treating participants with T-cell malignancies expressing the CD5 antigen.
